“Over the last two decades, Ethiopia has become a family planning success story, one of only a handful of countries in Africa to achieve that status,” David Olson, a global development communications consultant, and Andrew Piller, country director of DKT Ethiopia, write in the Bill & Melinda Gates Foundation’s “Impatient Optimists” blog. Noting their article, titled “Ethiopia: An Emerging Family Planning Success Story,” “is available in the December 2013 issue of Studies in Family Planning, published by the Population Council,” they say the “report chronicles the history of that success, identifies four key factors that produced those successes, and details how these factors interacted to expand access and desire to use contraceptives” (12/10).
